Due to the size of flag bits, I had to choose either /p or /m.
The only options I could make was:

  a) making /p obsolete; raise syntax error.
  b) making /p works as /m with warning

/p and /m are slightly different in behavior of ^ and $.
^ and $ does not match newlines in /p, they do in /m.
If these anchors do not appear in /p regexp, /m act just same.

And `m' stands for multiline, it works like Perl's /sm.
